Example of use: create a function to hide a mail address.

1. Create a class which implements ezcTemplateCustomFunction and which

will be included in your application (with the autoloading mechanism).

 1.  class htmlFunctions implements ezcTemplateCustomFunction
 2.  {
 3.      public static function getCustomFunctionDefinition( $name )
 4.      {
 5.          switch ($name )
 6.          {
 7.              case "hide_mail":
 8.                  $def = new ezcTemplateCustomFunctionDefinition();
 9.                  $def->class = __CLASS__;
10.                  $def->method = "hide_mail";
11.                  $def->parameters = array( "mailAddress" );
12.                  return $def;
13.          }
14.          return false;
15.      }
16.  
17.      public static function hide_mail( $mailAddress )
18.      {
19.          $old = array( '@', '.' );
20.          $new = array( ' at ', ' dot ' );
21.          return  str_replace( $old, $new, $mailAddress );
22.      }
23.  }

2. Assign the class to the Template configuration in your application.

1.  $config = ezcTemplateConfiguration::getInstance();
2.  $config->addExtension( "htmlFunctions" );

3. Use the custom function in the template.

1.  {hide_mail( "john.doe@example.com" )}

The generated html code for this will be: john dot doe at example dot com
